97.0. "clutch anyone ??" by BZERKR::DUFRESNE (You make 'em - I break 'em) Fri Mar 20 1987 19:33

    Ok.. this one is for the car freaks out there:
    
    	I am going to build a simple minded dynamometer to measure torque
    and RPM for my project (see note 93) 
    
    We have the torque watches. I need a clutch. I know that some cars
    are gas powered. how do you guys transfer power to the wheels ?
    
    I would find hard to believe that one just fires ups the engine
    and keep the wheels off the ground until you ready to roll.
    
    So ??
    
    tx in advance

	Centrigugal clutch,well that's what stops the rotors on my helicopter removing my kneecaps. 'Spect cars are the same. Bob (who still has a reasonable pair of knees)

	Went to hobby shop today.. bottom line is that cars & helicopters use same type of clutch: centrifugal. Kyosho is apparently the only mfg of gas powered cars. The parts catalog gives clustch in pieces, not as unit. And there is no parts explosion diagram.. I guess I get to call Great Planes .. Unless.... Its there someone out there with a car or heli out of commission that is willing to donate a clutch assembly to worthy cause?? md

	RE: all Are you sure that a clutch is what you want? Most Dynos. use a brake. The brake drag is varied to set the RPM at which to read the torque. A centrifugal clutch will just lock up (engage) above some RPM. Are we talking about the same thing? GES -+- \__[O]__/
97.5	yes we are..I think	BZERKR::DUFRESNE	You make 'em - I break 'em	`Wed Mar 25 1987 16:22`	6
	after some research, a centrifugal clutch may be what I want. I'm back to my orignal problem: DOes there exist a inexpensive Dyno set-up that I can use for my engine ?? Do they exist at all ?? md
